What did these deep thinkers have to tell us about, for example, the causes
of duodenal ulcers? Did they know it was mostly due to an infection by H.
pylori that could be cured by antibiotics? Oh wait, what did they have to
tell us about antibiotics? By the way, what *were* their views on the Weyl
tensor? (I know, that's a vile question.)

In other words: why should we care *what* they thought about issues that
can only be resolved by understanding the universe *based on the best and
deepest available information and theory* (and even that probably falls
well short of requirements)?
